Barred AGN galaxies in paired systems: exploring the impact on nuclear activity
Sol Alonso, Matias Vera-Rueda, Georgina Coldwell +2
Aims: To unveil the influence of galaxy-galaxy interactions on material transport driven by galactic bars towards the central regions of active galactic nuclei (AGN) galaxies and a…
Revealing ringed galaxies in group environments
Julia Fernandez, . Sol Alonso, Valeria Mesa +1
Aims. We explore galaxies with ringed structures inhabiting poor and rich groups with the aim of assessing the effects of local density environments on ringed galaxy properties. Me…
Enlightening the Universe behind the Milky Way Bulge
Fernanda Duplancic, Sol Alonso, Georgina Coldwell +7
Context. The location of the Solar System constrains the detection of extragalactic sources beyond the Milky Way(MW) plane. The optical observations are hampered in the so--called…
Properties of galaxies with ring structures
Julia Fernandez, Sol Alonso, Valeria Mesa +2
Aims: We present a statistical analysis of different characteristics of ringed spiral galaxies with the aim of assessing the effects of rings on disk galaxy properties. Methods: We…
Satellites and central galaxies in SDSS: the influence of interactions on their properties
Valeria Mesa, Sol Alonso, Georgina Coldwell +2
We use SDSS-DR14 to construct a sample of galaxy systems consisting of a central object and two satellites. We adopt projected distance and radial velocity difference criteria and…
Weak lensing analysis of galaxy pairs using CS82 data
Elizabeth J. Gonzalez, Facundo Rodriguez, Diego García Lambas +6
In this work we analyze a sample of close galaxy pairs (relative projected separation kpc and relative radial velocities km s) using a weak lensing analy…
The impact of bars and interactions on optically selected AGNs in spiral galaxies
Sol Alonso, Georgina Coldwell, Fernanda Duplancic +2
Aims. With the aim of performing a suitable comparison of the internal process of galactic bars with respect to the external effect of interactions on driving gas toward the inner…
The orientation of galaxy pairs with filamentary structures: dependence on morphology
Valeria Mesa, Fernanda Duplancic, Sol Alonso +3
Aims. With the aim of performing an analysis of the orientations of galaxy pair systems with respect to the underlying large-scale structure, we study the alignment between the axi…
LINER galaxy properties and the local environment
Georgina V. Coldwell, Sol Alonso, Fernanda Duplancic +1
We analyse the properties of a sample of 5560 LINER galaxies selected from SDSS-DR12 at low redshift, for a complete range of local density environments. The host LINER galaxies we…
Interacting galaxies: co-rotating and counter-rotating systems with tidal tails
Valeria Mesa, Fernanda Duplancic, Sol Alonso +2
We analyse interacting galaxy pairs with evidence of tidal features in the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7). The pairs were selected within by requiring a…
